The Advanced Micro Devices AM27C256-250-BXA is a high-performance 256 Kbit CMOS UV EPROM featuring a 32K x 8 memory organization. This component offers a maximum access time of 250 ns and operates asynchronously with a 5V nominal supply voltage. Designed for robust performance across a wide temperature range from -55°C to +125°C, it utilizes a ceramic DIP28 package with a window for UV erasure and through-hole mounting. Key specifications include a standby current of 120 µA and a maximum supply current of 50 mA. Applications for this UVPROM can be found in industrial control systems, legacy equipment, and specialized embedded designs requiring reliable, non-volatile storage. The component adheres to MIL-STD-883B screening standards.
